Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The LD50 dermal in the rat was greater than 2000 mg/kg bw.
- Executive summary:
The test of acute dermal toxicity was performed on a group of ten rats (5 male and 3 female) according to EEC Directive 92/69. The test material Bis(C12-C13)alkyl-2-hydroxybutandioate, was administered at a dose of 2000 mg/kg bw by dermal application. During the study no case of mortality occurred. No clinical symptoms were observed, the body weight gain was normal for the used species. At necropsy the animals showed no pathological symptoms and nothing abnormal was found.
The LD50 was greater than 2000 mg/kg bw and Bis(C12-C13)alkyl-2-hydroxybutandioate was found to be non-toxic under experimental conditions.
